De it known that I, ALBERT G. BREWER, of the city and county of Washington, District of Columbia, `have invented a new and useful improvement on the Quilting Machine for inserting steel or other wires into Leather; and I do hereby declare that the following is a full, clear, and enact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

The present invention relates to a machine to be used for inserting steel or other wires therein, the object being to increase the wear and durability ofthe leather; and the invention relates to or consists in a novel arrangement of mechanical devices, whereby the leather is fed through the machine so as to cause the wire to be forced into the leather by the die, as will be shown by the detail ldescription of the machine, reference being had to the accompanying plate of drawings, in whicl1- Figure 1 is a side view. i

Figure 2 is an end view (drawn full size) ofthe slide plate and working parts.

Figure 3 is a vertical view of the bed-piece.

Figure 4 is a view of the slide and die.

Figure 5 is a view of the wire-feeder.

Figure 6 is a view ofthe adjusting slide.

Fig. 1. A Arepresents the bed-piece on which the machine rests. B Bis an arm bolted on to the bed-piece A'A, reaching nearly across the bed-piece, and supporting the principal working parts. C is a pulley, where the power is applied to drive the machine. D is the main shaft, having-on the end D a crank t'o drive the slide F, which has connected to itthe die andwire-feeder. Gr is the feed-wheel, and is keyed to the shaft o, which is turned by the lever I, connected to the,v eccentric J, it having a pawl, K, and spring L, working into the ratchetwheel H, causing the shaft to revolve a certain distance at each revolution of the shaft D. M is a frictionscrew, keeping the eccentric stationary on the shaft D. When the machine is at work, the feed-wheel G presses the leather up against the end of the slide-plate K, where thewire is forced into it. The feed-wheel G is pressed up under the leather by a lever working under the shaft v at S, having a suitable weight attached to its opposite end. N is the wire-regulator,causing the wire forced into the leather to be longer or shorter, as required. An cud view is shownin g. 2, and sideyiew, full size, in iig. 6. This is made to slide out or in by the nut O working between Ythe slide-plate E and post o. Q is a friction-bolt, for keeping the wire in its place after being Afed to the cutter. P is a screw, used to keep a piece of steel that is dove-tailed into the slide-plate E in its place. This piece of steel is where the die and cutterwork, and is shown in fig. 2 by dotted lines 1 1. Fig. 2 is a front view ot' the slide-plate and working parts. M M are plates screwed on to the slideplate E, and keep the slide F in its-place. D represents the end ofthe shaft D, having the crank-wrist working in the Slot in the slide F, and causing it to work the die s, `shown in fig. 4. At the upper end of the die is a stud, 6, which keeps the die in its place, and when the die becomes shortened by wear can be lengthened by turning the stud, which has a slot in its end for the inserting of a screwdi'iver. Nreprcsents an end view of the wire-adjuster. It has a. piece of steel fastened on its side by screws, which isnarrowcr at the inner end, as represented in g. 6, its purpose being shown in a description of the working ot' the machine. c is a steel spindle running through the slide F, and has a spring, e, connected with it. A side view is shown in g. 5. The wire to be fed to the cutter' passes through the hole n in the spindle c. The pinf is to keep the spindle from turning round too far when at work. z'is an inclined plane on the slide F, which works the lever W. The lever works on the pin 2'; ils use is to work the slide-cutter X, which cuts thewire at Veach revolution of the shaft D. a is a spring, used t0` move the cutter X back after having done its work. Z7 is a pin in the cutter that the spring works against. Y

is a bolt, screwed through the lever W, and has a pinch-nut to keep it in its place. The object of this is to push the cutter its properdistance as it becomes shorter by use, the bolt being screwed through the lever further. T represents the wire t0 be cut and driven.

The operation of the machine is this: In iig. 2 the crank is represented at one-fourth stroke. It will be seen that the spring c is nearly in contact with the wire-regulator plate d, when the slide F moves down so that the spring e touches the wire-rcgulator d. It being a little too long to passby the plate d withoutsprii'xging, it will cause the spindle c to turn a little, andI the hole n in the spindle c, shown in iig. 1, being only a little larger than the wire, it willjam the wire so as to cause it to pass down with the slide F till the spring e passes the plate 0l; it then releases its hold. The hole u does not rnn exactly in the same direction as the wire, but so that when the slide is returning it will not jam the wire, but let it passthrough the hole n freely. When the slide F moves up about half its distance, the. end of the lever W cornes in Contact with the inclined plane z', causing the cutter X to eut and move the wire fed down under the die ready to be forced into the leather. When this is done it will be seen that the crank is at its top centre. When the slide F has been drawn to where it is rcpresented in lig. 2, the cutter will have been drawn back by the spring a, and the die will have commenced topush the wire cut down to be forced into the leather.

I claim as new, and desire to obtain by Letters `Patent- The combined arrangement of the spindle e, adjusting-slide N, and plate d, the adjusting-bolt Y, and adjusting-stud h, arranged substantially as and for the purpose described.
